Patent GB-2188168-A (GB)
Title: Image forming apparatus
Inventor: YAMAMOTO TAKEMI
IPC: G03F7/00
Filed: 1987-03-11
Abstract: A light- and pressure-sensitive recording sheet (16) and an original (14), overlapping each other, are introduced into the apparatus at (12), and are exposed to radiation on a transparent drum (24) by means of a light source (26) in the drum, to form a latent image on the material. Then, the recording sheet is separated from the original by means of a separator (28), and is passed between a pair of pressure rolls (34). When the recording sheet is exposed, microcapsules thereon change in hardness. These microcapsules are ruptured selectively by pressure applied to the sheet by the pressure rolls (34). As a result, a first composition, contained in the microcapsules, and a second composition, on the surface of a substrate of the recording sheet, react with each other, so that the sheet surface changes its color and a negative or positive colour image is produced. An auxiliary sheet may be fed between the pressure rolls to prevent recording medium dirtying the rolls. …<IMAGE>…

Title: Instantaneous water heaters
Inventor: CURRALL ALAN JAMES
IPC: F24H9/20
Filed: 1987-03-18
Abstract: An instantaneous water heater incorporates a flow sensitive device 9 positioned to monitor the inlet water flow, and a flow control valve 10, operable in response to changes in flow monitored by the flow sensitive device, to restore the flow rate to a set value. By this means, the outlet temperature of the water can be maintained approximately constant which is important when, for example, the heater is used with a shower unit and variations in the rate of water flowing to the heater occur when taps in another part of the building are opened. <IMAGE>
Patent GB-2192087-A (GB)
Title: Electronic drum
Inventor: NOMURA YOSHIO
IPC: G10H3/14
Filed: 1987-06-26
Abstract: In an electronic drum, a cushioning member (16), located within the drum shell (12, 14) to elastically support the cushioning/vibration composite plates (18, 20), includes an externally urging section (44) for externally urging the composite plates and an elastic support section (46) which, when receiving an external strike force exceeding a predetermined value, is elastically deformed. The externally urging section (44) may be a bellows. A sensor 24 does not produce an electrical output until the bellows is completely compressed by the strike force. When the strike force is increased to exceed the predetermined value, the elastic support section (46) elastically deforms, thus alleviating the reaction force against the strike force. The elastic support section may be apertured, to permit air flow. In another embodiment, the cushioning member comprises a ring-like air-filled tube which is substantially T-shaped in cross-section. The drum may be a snare drum or a bass drum.

Title: Temperature control of light-emitting devices
Inventor: DAKIN JOHN PHILIP
IPC: H05B44/00
Filed: 1988-08-24
Abstract: The temperature of the junction of a light-emitting semiconductor junction device 1 (e.g. an LED or laser diode) is measured by using the forward bias voltage/current characteristic of the device to provide an indication of the junction temperature and then controlling the temperature of the junction to a predetermined value in order to stabilise the output wavelength of the device. As shown the forward bias current of the device is measured by ammeter 3 and the forward voltage is measured by voltmeter 4. A signal processor 5 calculates the junction temperature and controls a temperature controller 6 to heat or cool the device. Alternatively the signal processor 5 may control the current source 2 and thereby vary the temperature of the junction by direct heating. <IMAGE>

Patent GB-885735-A (GB)
IPC: B01D53/24
Abstract: 885,735. Dynamo-electric machines. BRITISH OXYGEN CO. Ltd. July 31, 1959 [July 31, 1958], No. 24672/58. Class 35. [Also in Groups II and XL (a)] Rotary motion of a gas mixture to effect separation into heavier and lighter fractions is produced by a combination of travelling electric and magnetic fields, the travelling electric field serving also to ionize the gas. Rotary motion of the withdrawn gas fractions may also be utilized to generate electric power in passage through induction generator windings. The separation space may be cylindrical or annular as shown. In the chamber 13, which is symmetrical about the axis 10, the gas mixture is supplied at 12 and the heavier and lighter fractions are withdrawn at 15 and 16 at opposite ends of the space. Magnetic field windings 20, 22 mounted in slots in magnetic material 21, 23 are similar in form to the stator windings of an induction motor. The conductors 24, 25 for producing the electric field are located in slots within the insulating walls 18, 19 of the chamber. Both the electric and magnetic field windings are skewed in relation to the axis 10 so as to produce helical movements of the travelling fields in opposite axial directions along the inner and outer peripheries of the chamber. The windings are fed with polyphase current.
